U.S. imports of Halogenated, Sulfonated, Nitrated & Nitrosated Derivatives of Ketones & Quinones (NESOI) (HS 291479) totaled $15.3M in August 2026, imported from 14 countries.
Importers of Halogenated, Sulfonated, Nitrated & Nitrosated Derivatives of Ketones & Quinones (NESOI) paid $2.6M in duties in August 2026, an average duty rate of 16.66% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Halogenated, Sulfonated, Nitrated & Nitrosated Derivatives of Ketones & Quinones (NESOI) imports of $15.3M in August 2026 ran 51% above the year-to-date monthly average of $10.1M.
Last updated: August 2026 dataClassified as chemically modified ketone and quinone derivatives, this heading covers compounds where halogen, sulfo, nitro, or nitroso groups have been introduced — including 2,3-dichloro-1,4-naphthoquinone and artificial musks (2914791000), anthraquinone disulfonic acid sodium salt (2914793000), and other aromatic and non-aromatic derivatives. China and India are the leading suppliers, with Mexico also a notable source. Several compounds in this heading serve as intermediates for dyes, agrochemicals, and specialty polymers, making correct subheading selection critical because aromatic and non-aromatic derivatives are split across distinct 10-digit lines. Section 301 exposure applies to Chinese-origin shipments across much of this heading.

The US schedule separates other halogenated, sulfonated, nitrated, or nitrosated derivatives into aromatic (2914794000) and non-aromatic (2914799000) lines. The distinction follows standard organic chemistry definitions: aromatic compounds contain a benzene or equivalent ring system, while non-aromatic compounds do not. Importers uncertain about a compound's ring structure should obtain a binding ruling from CBP.
Yes — 2,3-dichloro-1,4-naphthoquinone and certain artificial musks are specifically enumerated under 2914791000, giving them a dedicated tariff line distinct from the broader 'other aromatic' catch-all at 2914794000. Importers should confirm the exact compound identity to avoid misclassification.
